					          Year 4                                                      Level 3 Outcomes

    Student Task

    There are many bridges built across the Brisbane River. Find out where these bridges are, what
    purposes they were built for and when they were built.

    Design a new bridge for Brisbane to service pedestrian traffic across the river between Southbank
    and the Mall.

    When designing your bridge consider structure, artistic quality and the needs of the area in terms
    of traffic, people, businesses…

    Unit Rationale
    Year 4 students are required as part of their school programs to study the community of their local
    area including groups within the community and needs associated with these groups. Bridges are
    often overlooked in a community as servicing needs, yet studies of the bridges in Brisbane will
    reveal the building of these structures based on community needs. Children will also gain an
    appreciation of the aesthetic appeal of many bridges and the association of well known bridges
    both in Australia and around the world with the cities where they have been built. In studying
    bridges, children will find that consideration has been given to climate, earth movements and
    landforms as well when constructing bridges. By studying the Brisbane River, children will
    become more familiar with their own community and gain an appreciation of bridge construction
    at the same time.

    Life-Long Learning

    This unit builds lifelong learner outcomes by:
   Encouraging children to gain in-depth knowledge of bridges and bridge construction and
    increasing their knowledge of their own area
   Developing skills of effective communication through spoken, visual and written means
   Encouraging children to become active investigators by visiting bridges along the Brisbane river
    and finding out when they were built and for what purpose
   Developing skills of critical thinking and decision making through participation in discussions and
    design processes
   Encouraging and developing skills as a reflective and self directed learner

Outcomes addressed in this unit

     SOSE: Level 3 Place and Space

     3.1 Students compare how diverse groups have used and managed natural resources
     along the Brisbane River
     3.2 Students create and undertake plans that aim to influence decisions about an
     element of a place such as a pedestrian walkbridge
     3.4 Students make and use maps to identify coastal and land features, countries and
     continents, and climatic zones
     3.5 Students describe the values underlying personal and other people’s actions
     regarding the local area
     3.7 Students describe how natural and built elements give character and importance to
     local and international places.

     SCIENCE: Level 2 & 3
     S.S. 3.3 Students make predictions about the immediate impact of some applications
     of science on their community and environment when building bridges.
     N.P.M. 2.3 Students explain why common materials are used in particular situations –
     materials used in bridges
     N.P.M. 3.1 Students examine and describe the smaller visible parts of common
     materials and relate these to the properties of the materials – bricks, cement, wood,
     N.P.M. 2.2 Students recognize ways in which changes in properties of construction
     materials occur including temperature changes.
     E.C. Students collect data and make and test inferences to describe the effects of
     forces on bridge construction and design

     HPE Level 3
     Health 3.3 Students recognize potentially hazardous situations relating to pedestrians
     in the city crossing the river. and demonstrate actions to respond to unsafe and
     emergency situations.

       Use the visual display of bridges around the world and across the
   Brisbane River to stimulate a class discussion on artist appeal. Discuss
   features that attract attention and look appealing – compare to those that
   don’ t appeal. Conduct a class survey to identify the most popular and
   least popular. Discuss why people feel that way and draw conclusions
   about the style or styles of bridges that might suit our task.
        Make a list of materials used to build bridges. Conduct experiments to     Wood, cement, samples of        Science Knowledge
   determine the properties of these materials and suggest reasons why these       metals, cardboard, plaster,     Observation
   materials would be used rather than different metals or combinations of                                         Drawing conclusions
   materials.                                                                                                      Discussions
        Conduct experiments to determine the strongest structures of bridges       Paper, P.I activities           Investigating
   using common structures. Set a task to use straws to build three different      Straws, sticky tape             Predicting
   types of bridges and see which can hold the greatest weight. Investigate
   your own structures and compare the results.
        Observe bridges across the Brisbane River and world wide to identify       Art activities – symmetry and   Application of maths concepts
   shapes used in the design and symmetry incorporated into the design.            shapes, tessellations,

Synthesizing Phase:
        Draw a plan for a pedestrian bridge based on the information gained so     Design booklets – prepare in    Technology Design – see
   far. Include artist appeal, structure, shapes and symmetry.                     advance with pages to           assessment matrix
        Present the design as a 2D drawing with labels to identify features.       complete on design, reasons,
        Plan and draw an aerial view or model of the bridge as seen from the       materials, aerial view etc.
   news helicopter.
        Make a list of materials that would suit the construction of your bridge
   and include an explanation of why these were chosen.
        Present your plan to the class along with the drawings and aerial view
   or model as though you were presenting it to council.

Invite the local councillor along to view your completed designs.
